IMPROVEMENT lN DUST-CONVEYERS FOR THRASHlNG-MACHINES.

Specification forming part of Letters Patent No. 127,884, dated J nne 11, I872.

loall whom it may concern:

Be it known that I, JACOB B. HUNSBERGER, of Vincent, in the county of Chester and in the State of Pennsylvania, have invented certain new and useful Improvements in Dust-Conveyer for Thrashing-Machines; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon making a part of this-specification.

The nature of my invention consists in the construction and arrangement of a dust-conveyer for thrashing-machines, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention 'appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure 1 is a side elevation of a thrashingmachine with my dust-conveyer attached thereto. Fig. 2 is a transverse vertical section, and Fig. 3 a longitudinal vertical section, of the dustconveyer.

A represents a thrashing-machine of any desired construction, of which B is the feed-table, O the thrashing-cylinder, and D the tail end. The entire machine in rear of the thrashingcylinder is covered by an inclined sheet-metal cap, E, so that all dust arising from this part of the machine will be carried toward the center and up the conveyer. sists of an upright box, H, fitting transversely across the thrashing machine and its lower and divided into two curved flues, Gr Gr, the mouths of which fit one at the inner end of the inclined cap E and the other over the inner end of the feed-table B, so that the dust from either end of the machine will pass upward through said flues into the box H. A suitable distance above the flues G G and in the box H are deflecting-boards I I, inclined as shown in Fig. 2, dividing the box actually into two compartments, J J. Between the upper ends of these two compartments is placed a box,

. K, containing a fan, L, which, by suction,

The conveyer condraws the dust up into said box, the compartments J J opening into the same. The fan L is attached to a shaft, a, passing horizontally through the upper end of the conveyer, and from said shaft vertically downward through each of the compartments is a plate, b, extending clear down to the point where the flues G G join, thus actually dividing the conveyor and forming continuations of said 'flues G G, so that the dust from the two ends of the thrashing-machine will not mix or commingle until the currents enter the fan-box K. From this box the dust is blown out through the spout M, which is placed over the box K and fan L, and may be turned in either direction, as shown in Fig. 1, so as to carry the dust out on either side of the barn, as may be desired. When the spout M is reversed the motion of the fan L must also be reversed, which is readily accomplished by twisting the cord or belt (I, which communicates motion from the drivingshaft of the thrashing-machine to the fan.

The conveyer may be held to the thrashingmachine and the spout to the conveyer by means of hooks, as shown, or by any other suitable means.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In combination with the feed and discharge openings of a thrashing-machine, the dusting attachment herein described, consisting of the conveyer H, deflecting-boardsI I, plates 1) b, and box K, with fan L and spout M, substantially as and for the purposes herein set forth.

2. The reversible spout M covering the fan L, constructed and arranged substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 21st day of March, 1872.

JACOB B. HUN SBERGER.
